FIELD OF INVENTION

Embodiments of the present disclosure relate to sport accessories, andmore particularly to, a smart cricket bat and a process of fabricationof the same.

BACKGROUND

Cricket is a game played with a bat and a ball between two teams. Eachteam includes eleven players. Cricket is viewed by millions of peoplearound the world. Due to the worldwide popularity the game has gainedover the years, many individuals aspire to represent their country andtrain in that direction. Training involves for instance, attending acricket camp organized by veteran bowlers and batsmen, often referred toas coaches, having played the game of cricket in different forums andlevels. The coaches train individuals to become bowlers or batsmensubsequent to testing the individual's potential. If the coachascertains that the individual would be a good fit as a batsman, thenappropriate training would be provided in this regard.

The individual would be trained with respect to playing different typesof shots, swing movement of the cricket bat, etc and relevant feedbackwould be provided to the individual regarding the performance. Thefeedback provided is mainly based on observations by the coach. Now adays, due to many individuals attending cricket camps, the coaches mayhave to train multiple individuals simultaneously. Therefore, there havebeen instances of the coach, failing to observe certain parameters whichare critical for the batsman, thereby not providing proper feedback tothe individual, thereby hampering the individual's growth as a batsman.The other option would be to attend camps which provide personalizedtraining, which of course would be expensive and not affordable by many.Moreover, even then there are possibilities of human error by the coach.

Further, to overcome the aforesaid issues, various solutions have beenimplemented in the past by coupling sensing mechanisms to the cricketbat, which would provide performance related data with respect tobatting. However, such sensing mechanisms being detached from the batand falling on the stumps due to impact of the ball. Also, such sensingmechanism causes an increase in dimension of the bat which is notallowed as per the Marylebone Cricket Club (MCC) rules. Moreover, suchsensing mechanism causes discomfort to the batsman while playing shots.

Hence, there is a need for an improved smart cricket bat and a processof fabrication of the same in order to address the aforementionedissues.
